Exercise
Take G = S4 and N = {e, (1,2)(3,4), (1,3)(2,4), (1,4)(2,3)}. Then N is a normal subgroup of G. To which group is the quotient group G/N isomorphic?
{e}
The cyclic group of order 6.
Z/6Z
S3
No. The quotient group is not commutative.
No. This (additive group) is als the cyclic group of order 6.
Right.
